Abstract:
An access control apparatus for an access gate. The access gate typically has a rotator that is configured to rotate around a rotator axis at a first variable speed in a forward direction. The access control apparatus may include a transmission that typically has an input element that is operatively connected to the rotator. The input element is generally configured to rotate at an input speed that is proportional to the first variable speed. The transmission typically also has an output element that has an output speed that is higher than the input speed. The input element and the output element may rotate around a common transmission axis. A retardation mechanism may be employed. The retardation mechanism is typically configured to rotate around a retardation mechanism axis. Generally the retardation mechanism is operatively connected to the output element of the transmission and is configured to retard motion of the access gate in the forward direction when the first variable speed is above a control-limit speed. In many embodiments the transmission axis and the retardation mechanism axis are substantially co-axial. Some embodiments include a freewheel/catch mechanism that has an input connection that is operatively connected to the rotator. The input connection may be configured to engage an output connection when the rotator is rotated at the first variable speed in a forward direction and configured for substantially unrestricted rotation when the rotator is rotated in a reverse direction opposite the forward direction. The input element of the transmission is typically operatively connected to the output connection of the freewheel/catch mechanism.

Abstract:
The invention relates to a drive arrangement for the electric adjustment of a functional element (1) in a motor vehicle. A drive motor (2), which adjusts the functional element (1) in an electrical manner in two adjustable directions, is provided and the drive motor is drivingly coupled to the functional element (1) by means of a first drive train (3) and a second drive train (4). The drive force is transmitted, simultaneously via the two drive trains (3, 4), at least in an adjusting device, during the electrical adjustment of the functional element (1). One of the two drive trains (3, 4) comprises a cable pull transfer (5) comprising a drive cable (6) which is used to transfer drive force. According to the invention, only one of the two drive trains (3, 4), primarily the second drive train (4), has a cable pull transfer (5) which is used to transfer drive force and the first drive train (3) is embodied in a cable pull free manner.
Abstract:
An electric roller door drive system (10) is described enabling also selective manual operation of the associated door by means of a manual drive wheel (26) coupled to a power output (18) (which the motor (16) can also drive) so as to enable manual movement of the door between the open and closed positions. A clutch mechanism (30) has a normal default condition and an electrically initiated motor drive enabling condition, the clutch mechanism in the normal default condition enabling the manual operation and, in its motor drive enabling condition, functioning so as to firstly disable the manual drive mechanism so that manual rotation of the manual drive wheel (26) does not transfer drive through the power output (18) to move the door; and secondly enable operation of the drive motor. The clutch mechanism is electrically operated to change from its normal default condition to its motor drive enabling condition when the electric drive mechanism is to be operated to drive the associated door between its open and closed positions. The manual drive wheel (26) in the normal default condition of the clutch is biased by a biasing spring means (31) into its operative position, and electrornagnetically operable displacement means (41) is operative upon supply of electric power thereto to displace the manual drive wheel against the bias of the biasing means away from its operative position and into its idling position.
Abstract:
Die Erfindung betrifft einen Türantrieb, insbesondere die Türverriegelung, von Schienenfahrzeugen, aufweisend einen Spindelantrieb, dessen Spindel mit einem Freilauf verbunden ist, der die Drehung der Spindel in der Richtung, die der Schliessrichtung der Tür entspricht, gestattet und die Drehung der Spindel in der Richtung, die der Öffnungsrichtung entspricht, verhindert, wobei der spindelferne Teil des Freilaufs (1) drehbar, aber durch eine von einem Hubmagneten (8) lüftbare Kupplung (3, 6) lösbar fixiert bezüglich einer Lüftungsvorrichtung (2) gelagert ist. Die Erfindung ist dadurch gekennzeichnet, dass die Bremse, Kupplung od.dgl. in ihrer Offenposition fixiert oder fixierbar ist, und dass ein Schliessmagnet vorgesehen ist. In einer ersten Variante ist die Kupplung (3, 6) durch ein Gestänge (9) betätigbar, und zwischen der gelüfteten Position des Gestänges (9) und der verriegelten Position des Gestänges (9) liegt eine Totpunktlage. In einer zweiten Variante wird die Offenposition durch einen Permanentmagneten gehalten.
Abstract:
An operating mechanism of an open/close body, comprising a drive means for drivingly opening an open/close body, a position detection means for detecting the opened position of the open/close body, and a full open position storage means for storing the full open position of the open/close body, wherein when the open/close body is drivingly opened by the drive means, the drive means is stopped at a full open recognition position stored in the full open position storage means or at a position a specified amount before the full open recognition position, and when the present position of the open/close body after the drivingly opening by the drive means is completed is different from the full open recognition position (#1), the full open position storage means sets a new full open recognition position (#2).
Abstract:
A power drive assembly moves a liftgate (12) of a motor vehicle (10) between its open and closed positions. The motor vehicle (10) defines an opening and the liftgate (12) closes the opening when the liftgate (12) is in its closed position. The power drive assembly (22) includes a base (24) that is fixedly secured to the motor vehicle (10) at a position in spaced relation to the opening. A drive mechanism (38) is fixedly secured to the guide. The drive mechanism (38) converts electrical energy into a linear force. The power drive assembly (22) includes a translation linkage (58) connected to the drive mechanism (38) for receiving the linear force and translating it into a nonlinear force to move the liftgate (12) between the open position and the closed position. A nut (52), secured to the translation linkage (58), moves the translation linkage (58) as it travels along a lead screw (50) that is rotated by a motor (40).
